Regarding house building, there is only so much that can be pre-produced. Assembly is still on site, and that will always require rework, nobody can affors the site preparation and parts manufacture at the required tolerance levels to avoid that.
I didn't say anything to contrary. I am saying that car factories can churn out high quality welds at scale, but construction companies can't.

It looks like 'only so much' can go pretty far.
Eg camper vans have also become a lot better over the years. They benefit from not being banned in the US.
